Acute gastroenteritis, due to spasms in the gastrointestinal tract, involves significant pain. If the intestinal inflammation is minor, the symptoms of abdominal pain usually improve noticeably after defecation. However, if the inflammation is severe, the abdominal pain can be intense, with more frequent episodes of diarrhea, and the pain lasts for a longer duration. Medical treatment involves using medication to relieve spasms and pain, using antibiotics to eliminate the inflammation, and appropriately supplementing fluids to maintain the balance of water and electrolytes. If necessary, spasm-relieving medication can be administered by injection. At the same time, it is important to maintain a reasonable routine, ensure plenty of rest, and observe a good prognosis with active treatment. (Note: Medications should be used under the guidance of a doctor based on the specific condition.)
